Amish Apple Pie

Why I Love This Recipe
This is one of the very first pies I ever made. It is delicious and is like apple dumpling with custard sauce. I hope you love it like I do!
Ingredients You'll Need
Streusel:
1/3 cup granulated sugar
1/4 cup brown sugar
1/2 cup plus 2 tbls flour
1 tsp ground cinnamon
1 tsp grated nutmeg
Speck of salt
1/2 cup (1 stick) butter, cold
1/2 cup coarsely chopped walnuts
Filling:
4 large apples, McIntosh or Granny Smith (4 cups)
1 unbaked 10 inch pie shell
1 cup granulated sugar
3 tbls flour
1/2 tsp ground cinnamon
1 egg
1 cup heavy (whipping) cream
1 tsp vanilla extract
Directions
In a food processor bowl, mix the first 6 streusel ingredients.
Add the butter and process until the mixture is crumbly; it should still
have a dry look to it -- don't over process.
Add the nuts then set aside. (I do this process by hand. I like my streusel in large pieces. I don't think a processor gives a great streusel. I recommend do it by hand and work the butter in)
Preheat oven to 350 degrees F.
Peel, core and thinly slice apples;
There should be 4 cups.
Place apples in the pie shell.
In a small bowl, mix the sugar, flour, and cinnamon.
Beat the egg in a medium bowl, and add the cream and vanilla.
Add the sugar mixture to the egg mixture and blend.
Pour over the apples.
Bake for 1 hour in the
lower one-third of the oven.
After 20 minutes, sprinkle streusel over the top and continue baking
approximately 40 minutes longer, or until the top puffs and is golden brown.
Enjoy.
